XLPE DS, 5, 15, 25 and 35 kV type Medium Tension

90 °C

General description

Single-conductor cable manufactured with one soft copper or hard 1350 alloy aluminum conductor with sealing material, semi-conducting shield and cross-linked polyethylene (XLPE) insulation, extruded insulation shield, metallic copper stranded shield and polyvinyl chloride (PVC) jacket.

Specifications

  • Viakons shielded and jacketed XLPE DS type medium voltage cables meet the following specification:
  • NRF-024-CFE Single conductor power cables from 5 kV to 35 kV.

Main applications

  • Underground primary distribution networks in commercial areas with a very high load density.
  • Primary electrical energy supply and distribution in industrial plants.
  • Primary distribution networks in residential areas.
  • Electrical power supply and distribution for buildings with substations located on different levels.
  • Can be installed in conduits and ducts.

Characteristics

  • Maximum operation voltage: 5 000, 15 000, 25 000 or 35 000 V.
  • Insulation levels from 100% to 133% (categories I and II respectively).
  • Maximum operation temperature: 90°C.
  • Maximum operation temperature in an emergency: 130°C.
  • Maximum operation temperature in short circuit: 250°C.
  • Soft copper or hard 1350 alloy aluminum conductors with tightly applied concentric strands in sizes from 8,367 to 506,7 mm 2 (8 AWG to 1 000 kcmil).
  • Cross-linked polyethylene (XLPE) insulation.
  • No-flame polyvinyl chloride (PVC) jacket.
  • Red jacket.
  • Can also be manufactured with black polyethylene with 3 red stripes along the cable.
  • Notes:
  • 1) This product can also be manufactured with blocking elements to keep water away from the metal shield (used in damp or wet environments).
  • 2) This products can also be manufactured with tree retardant cross linked polyethylene (TR-XLPE) as insulation.

Advantages

  • Metallic shield:
  • Provides an excellent ground connection, which improves personal safety conditions during the operation of the cable.
  • Confines and equalizes the electrostatic field.
  • Protects operating equipment from electrical failures
  • Jacket provides mechanical protection against abrasion and mal-treatment during installation.
  • Anti-flame jacket makes it resistant to weather, sunlight, and chemical agents.
  • Suitable for direct burial.
  • Excellent electrical and mechanical characteristics.
  • Low dielectric losses.
